It's hard to compare Jimi to anyone because he was so original in his time. Stevie Ray Vaughn is probably is a good comparison (and probably my favorite). Similar style. But Jimi was absolutely SRV's main influence. Jimmy Paige is kinda similar in that he would do some weird s**t with his guitar too. If your talking about innovators then I'd say Eddie Van Halen. He influenced a ton of people too.
